  • How to calculate a modulus
  • Math.random()
  • binary to decimal
  • decimal to binary

  • How to ask the user for input using a Scanner object.
  • Add Fractions problem: create this in sandbox environment in codehs and share with me.
    • Directions: In this program you will ask the user for 4 integers that represtent two fractions. First ask for the numerator of the first and then the denominator. Then ask for the numerator and denominator of the second. Your program should add the two fractions and print out the result. For example: a sample program run might look like this,

Numerator One: 1

Denominator One: 2

Numerator Two: 2

Denominator Two: 5

The sum is 9/10

//rememember if you have two fractions, the following formula should be used: a/b + c/d = (a*d +b*c) / b* d

public class MyProgram

{

   public static void main(String[] args)

   {

      //Ask the user for 4 numbers. (don't forget to import your Scanner class)

 

 

     //create your final numerator

 

    //create your final denominator

 

   //print out your result like the example above
